Recent Comments – links in right side bar

Hi all, I think I may have broke something. When you click on one of the recent comments in the right sidebar of this page, the link doesn’t take you to the comment section at the bottom of the page. How can I make the links work again? For instance, one of the comments says “SANDigz on Adventure Sandbox” when someone clicks on SANDigz or Adventure Sandbox I would like the link to scroll to the bottom of the page. Is this related to my wordpress.org profile or the wordpress.com Gravatar?
